' 4 Claims. (01. 20-42 This invention relates to frames for windows,doors, storm sash, screens, -etc., and has for its object to provide animproved simplified construction-for making sash frames. I 5 A furtherobject of this invention is to construct a frame with novel metalcorners which, besides holding the rails of the frames together,increases the rigidity of the frames by reinforcing the corners thereof.

10 Another object of this invention is to provide the frame with novelforms of rails in combination with metal corners which permit the railsto be accurately fitted on all sides of the frame including the cornersthereof.

15 These and other objects and attendant advantages of the inventionwill become more readily apparent from the detailed description thereofwhich follows, reference being had to the accompanying drawing in which:

Figure 1 is a perspective front view of the corner construction of aframe in accordance with my invention.

Figure 2 is a perspective rear view of the cor--.

,In the several figures of the drawing like ref 35 erence numeralsindicate like parts.

The construction of the frame forming the subject matter of thisinvention includes the use of rails of uniform cross section for thesides,

top and bottom of the frame. These rails, indi- 40 cated by referencenumeral I and illustrated in cross section in Figures 3 and 4, have aportion of their outer edge cut away to provide a rabbet 2 thereon witha narrow groove 3 extending into the rail at the inner edge of therabbet parallel 5 thereto. In this way each rail is provided with afitting ridge or ledge 4 on the outside thereof.

The inner edge of each rail is rabbeted at 5 to have the molding 6 nesttherein and clamp the edge of a screen I to the rail. On the inside of 5the rail parallel to the rabbet 5 and suitably spaced from it is thenarrow groove 8. This groove is thus located on the inside of the railsubstantially opposite to the groove 3 provided in the outside of therail. In the construction 55 of a frame the ends of the rails arebrought tomeans of this ridge. slightly larger thanthe opening intowhich it is 25 together make this possible.

gether in a miter joint and'the mitered ends are held together by acorner bracket 9. These brackets are formed of sheet metal and provide arectangular channel with flanges l0, I0 over- U hanging the channel asillustratedin Figure 5. 5 In connecting a pair of rails the mitered endsthereof are telescoped from opposite" ends into the rectangular channelof the corner bracket 9 with theflanges I'll, It thereof projecting intothe grooves 3 and 8 in the rails. After the rails 10 are broughttogether in the corner bracket in this Way nails or screws are driventhruthe metal back or sides thereof into the rails to lock the I ends ofthe rails in place in the bracket and cause 2 them tobe rigidlyconnected and held in place in the bracketat right angles to each other.

With the rails fastened togetherin this manner, the fitting ridge 4 ofeach rail extends beyond the outside of the metal corner brackets whichhold the rails together so that this fitting ridge continuously extendsaround the completed frame to provide for an accurate fitting of theframe into a window or door. frame by The frame is usually made to befitted and thefitting'ridge make'sit possible to accurately finish theedge of the frame to its proper dimension after it has otherwise beencompleted. The use of the novel. metal corners and the manner in whichthey hold the rails In Figure 3 reference numeral .ll indicates thecrosssection of a window or door frame into which a frame,

made up in accordance With my invention, is

fitted as above pointed out.

When a'glass panel I2 isto be mounted in the frame as illustrated incross section in Figure 4, the rabbet 5 is provided with a shoulder l3so as to have the mold l4 provide a channel between it and the rail I inwhich the glass panel 40 is held in placewhen the molding is fastened tothe rail by suitable wire nails l5.

The shoulder l3jis preferably provided by a spacing strip It which isplaced or'fastened into the rabbet 5. The spacing strip used is slightlythicker than the thickness. of theglass panel which is to be mounted inthe frame so that when the moulding. I4 is fastenedjin place it cannotexert pressure on the edge'of the panel and thereby cause it to break. Iclaim:

1. A frame made up of a plurality of rails of uniform crosssection-having a rabbet on the outer edge of each rail on one sidethereof, a locking groove extending inwardly of the inner corner of therabbet, a second locking groove on the inner edge of each railintermediate the sides thereof and substantially opposite to said firstlocking groove, locking brackets connecting said rails by engaging oneside and the outer and inner edges of adjacent rails, each lockingbracket comprising an angular channel, flanges on-the sides of saidchannel arranged to partially overhang said channel, said flangesengaging into said locking grooves to guide and hold the sides of saidchannel against the outer and inner edges of said rails in said lockingbracket.

2. A frame made up of a plurality of rails, a locking groove in one edgeintermediate the sides of said rails, a rabbet in the other edge on oneside of said rails, a second locking groove extending inwardly of theinner edge of said rabb'et to- Ward said first locking groove, a lockingbracket embracing one side of said rails, the bottom of the rabbet and aportion of the inner edge of said rails, and means provided on saidlocking.

bracket to engage said locking grooves to hold said rails in saidlocking bracket in a predetermined position with relation to each other.

3. A wood frame made up of a plurality of rails having a uniform crosssection, metal brackets embracing one side and part of the outer andinner edges of the ends of successive rails on the outside and inside ofthe frame with a portion of the outer edge of each rail projecting pastthe parts embraced by the metal brackets to pro vide a fitting edgearound the frame and locking means cooperating with said brackets tolock said brackets to said rails.

4. A wood frame made up of a plurality of rails having a uniform crosssection with a projecting fitting edge, metal brackets embracing oneside and part of the outer and inner edges of the ends of successiverails on the outside and inside of the frame and within the projectingfitting edge of the outside of the frame so as to keep the fitting edgeof the frameexposed over its entire perimeter and locking means carriedby said metal brackets to lock said brackets to said rails.
